... Electrochemistry and Energy Systems (CLEPS), Bulgarian Academy of Sciences, 1113 So a, Bulgaria Available online 20 December 2005 Abstract The effect of polyaspartate (PASP) on the performance of the lead-acid ... The addition of PASP leads to formation of smaller PbSO 4 crystals, which are more easily reduced during charge and hence prevents the accumulation of large lead sulphate crystals...
